Most CMP APIs (*.list operations) support the filter parameter to make it easier to find the information you need. While filters are powerful, there are few caveats to remember:

Different keys in the same filter will do “AND”

Example: Using platform:google-cloud|status:archived as a filter will filter the list of objects that are both for google-cloud AND have archived

Same key multiple times in the same filter will do “OR”

Example: platform:google-cloud|platform:amazon-web-services will return Known Issues that are from google-cloud OR amazon-web-services

Having multiple keys multiple times is not supported

Example: In platform:google-cloud|platform:amazon-web-services|status:archived|status:active, there are two “platform” and two “status” filters, and this is not supported in the CMP API. Using such a filter will result in an error.

The correct use of the filter in this case would be platform:google-cloud|platform:amazon-web-services|status:archived
